GCompris: Adding New Activities
Project Overview
GCompris is a high quality educational software suite, including a large number of activities for children aged 2 to 10, some of the activities are game orientated, but nonetheless still educational.
Currently GCompris offers more than 150 activities, and more are being developed. GCompris is free software, it means that you can adapt it to your own needs, improve it, and most importantly share it with children everywhere.
My project goals include adding four new activities to GCompris:
- Subtraction decimal number activity.
- Addition decimal number activity.
- Programming maze loops activity.
- Mouse control action activity.
Learn decimal numbers
In this activity, a decimal number is displayed. the bar with the arrow represents a full unit, and each square in it represents one tenth of this unit, the kid has to drag the arrow to select a part of the bar, and drop the selected part into the empty area so that the number of dropped bars corresponds to the displayed decimal number.
For every dropped bar, all bars are organized after 1 second from the drop action such that the kid can see the reorganization of bars, as a result we add a place for a 6th bar to have at most 5 full bars.
The activity provides instruction tutorials on how to play with it, both vertical and horizontal layout are supported.
Learn addition for decimal numbers
In this activity, an addition with two decimal numbers is displayed, and the kid has to represent the result of the addition by dragging bars into the empty space, in case he represents the result correctly, he is asked to type the corresponding result.
Learn subtraction for decimal numbers
In this activity, a subtraction with two decimal numbers is displayed. Below it, the first number from the subtraction is represented with bars, the kid has to click on the squares to represent the result of the subtraction.
A cross is added to all square units after the clicked square such that the kid can visualize what has been removed from the first decimal number, if he represented the result correctly then he is asked to type the corresponding result.
